FOUNTAIN PEN. H

Application filed March a,

, is simple and therefore economical to manufacture.

A further object of the invention is to produce a device which may be applied to the ordinary fountain pen without materially altering its construction;

Other objects and advantages will be apparent during thecourse of the following description. I I

In the accompanying drawings forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same,

Figure,-I 1s a vertical cross-section of a fountain pen constructed in accordance with my invention,

Figure II is a vertical cross-sectionof a cartridge constructed in accordance with my invention, and A Figure III is the end view of the tip portion of my pen.

At the present time it is common toemploy fluid ink in'a bottle or like container, which ink is soaked up into the, pen by em, ploying a depressed rubber sack within the pen, or else by employing a dropper which first sucks u the ink and later dispenses the same into the barrel of the pen. Both of these methods are very inconvenient, in that the hands are soiled during the filling-process. f Withmy invention this inconvenience is entirely. eliminated. I employ a cartridge which is preferably made of thm metakfilled with ink and then hermetically sealed at one end with a thin tip or ladcapI which is capable of being punctured when it is dQSlIGd to use the contents of the cartridge. In the accompanying drawings wherein for thepurpose of illustration is shown a preferred embodiment of my invention, the

of the pen to which a tip 6 is preferably secured, WhlGh. tip has'theusual spoon 7 extending therethrough, which spoon overlies a pen point 8.

The inner end of the tip 6. is reduced and threaded and the threaded portion has formed thereon a tapered inner .end which terminates ina penetrating point, and the tapered end is formed with converging openmgs or bores communicating at their inner ends and with a groove formed longitudinally in the spoon as suggested in Figlre 1.

1} cap 12 is threadedly engaged with the por tion of the em and serves the function formln a cartridge as shown at 13 in the barrel of t e pen. This cartridge has one end closed as at 14 and has its opposite end closed as at 16by a relatively thin wall which may be readily punctured.

The manner of using my device is as fol Assuming the pen to be constructed in accordancewith Figure I; the cap 12 is removed, the old cartridge withdrawn and thrown away and a new cartridge inserted within the pen, after which the cap is replaced and screwed on the pen body. This will force the cartrid e against the point 9 which willpuncture t e wall 16 thus releasing the contents of the cartridge which will flow through the lateral o emngs or bores and groove 11 of the spoon to the pen point "It will thus be seen that 1.11m produced a simple device which will accomplish all of the objects herein mentioned.

' It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes relative to the size, shape, .material and arrangement of parts may be resorted to-without departing from the spirit of the inventionor the scope of the subjoined claims.

Having thus described my invention, I claim 2:-

In a fountain pen, the combination .with a barrel, a tip threadedly secured in one end of the'b'arrel and having a tapered end termiriating in a penetrating'point disposed contrally of the'barrel at'the tip receiving end thereof, said tapered end having conver 'ng bores. disposed in communication at t eir ynumeral Sdesignates the mainbarrel portion inner ends, a spoon received in said tip and being formed with a groove adapted to 'communicate With'the communicating ends of the bores, a cap threadedly secured to the opposite end of the barrel, a cartridge. having one 5 end closed and a relatively thin Wall for the opposite end thereof, and said cartridge being adapted to be. positioned in said barrel and moved by the cap to cause the penetrating point to penetrate the thin wall to allow for the flow of fluid in the cartridgethrough 10 the bores and groove of the s oon. 1

In testimony whereof I ax my signature.

CHARLES W. HORN.
